This study focused on the determination of secondary metabolites to an evaluation of the biological activity of Elaeocarpus variabilis Zmarzty fruit extract, an endemic medicinal plant. Their total Phenolic, tannin, flavonoids, alkaloids and saponins contents were quantified and their antioxidant activity, determined by DPPH, total antioxidant, ABTS, FRAP and Fe2+ chelating activity. The ethyl acetate extract exhibited the highest radical scavenging activity. The most relevant contents in total phenolics (Gallic Acid Equivalent mg/g), tannin (Gallic Acid Equivalent mg/g), total flavonoids (Rutin equivalent mg/g), total alkaloids (Quinine equivalent mg/g), and total saponin (Diosgenin equivalent mg/g) were observed. Significant correlations were established between antioxidant activity and secondary metabolites. Though the in vitro anti-diabetic activity was carried out using -amylase and -glucosidase inhibition, this indicates that the absorption and digestion of carbohydrates would probably reduce the blood glucose levels and hence help the management of type-2 diabetes. The ethyl acetate extract exhibited the potential of anticancer activity on human HT-29 colon cancer cell line IC50 values (30.0 ± 1.0) the valuable activity that compared to doxorubicin (17.0 ± 0.5). While this is the first study concerning extract from E. variabilis, our findings highlighted the richness’ in flavonoids of those extracts and their amazing potential as a source of antioxidant, anti-inflammatory, anti-diabetic, and anticancer agents.

Gülten Tiryaki Gündüz | Burcu Sıla Göral
Grape pickle is a traditional food that is made with grapes (Vitis vinifera), horseradish (Armoracia rusticana) and grape syrup. In this study, the survival of Bacillus cereus and Escherichia coli in grape pickles produced with or without using probiotic Lactobacillus acidophilus La-5 as well as microbiological, chemical and sensory properties of each group were examined during 35 days of ripening at 25°C and 5 months at refrigerated storage period. Molds and lactic acid bacteria (LAB) counts remained below the limit of detection (6 log in samples to be considered a probiotic product. E. coli counts rapidly declined to undetectable level within 7 days, while B. cereus numbers was found 1.56-1.72 log cfu/g at the end of the storage period. As a result, it was established that traditional grape pickle is not suitable food matrix for probiotication. High total soluble solid content (63 °Brix) and presence of horseradish in grape pickles ensure the microbiological stability as well as the safety of product.

This study was carried out to determine the effects of different doses (10, 20 and 30%) of sumac shrub leaf substitution instead of corn silage in sheep rations on in vitro gas and methane production, metabolic energy (ME), net energy lactation (NEL) and organic matter digestion degree. Sheep ration consisting of corn silage (20%), alfalfa straw (22.5%), dry meadow grass (20%), and commercial feed (37.5%) constituted the control group. The experimental groups were formed by substituting 10 (S1), 20 (S2) and 30 (S3) percent sumac shrub leaves for corn silage in the control (C) group formed the experimental groups. The effect of sumac shrub leaf substitution on in vitro gas and methane production, metabolic energy, net energy lactation, and organic matter digestion degree was found to be significant. The 24-hour in vitro gas production values of rations ranged between 43.11- 46.77 ml/200 mg DM, methane production values 6.8-7.48 ml, metabolic energy values 8.91-9.41 MJ/kg DM, net energy lactation, 5.59-5.95 MJ/kg DM and organic matter digestion degree values found between 64.25 and 67.61%. As a result, it was determined that increasing doses of sumac shrub leaf substitute reduced gas and methane production. In addition, it was concluded that the data obtained should be supported by determining the microorganism counts, feed consumption amounts, and feed efficiency coefficients with in vivo studies.

This study was carried out in 2019 to determine the effects of methyl jasmonate (MJ), gibberellic acid (GA3) and naphthalene acetic acid (NAA) applications on fruit yield and essential oil content in anise (Pimpinella anisum L.). Different concentrations of MJ (0, 0.1, 0.5 and 1 mM), GA3 (0, 50, 100 and 150 ppm) and NAA (0, 25, 50 and 100 ppm) were pulverized to the plant during the beginning of the flowering. Phytohormone applications had a statistically significant effect on the parameters examined in the study, and the effects of the applications generally varied depending on the application doses. While GA3 and NAA applications significantly increased the fruit yield and essential oil content compared to the control, high-dose MJ applications generally had a negative effect on all parameters except that the thousand-grain weight. The highest fruit yield was obtained from 100 and 150 ppm GA3 and 25 and 50 ppm NAA applications, while 1 mM MJ applications significantly reduced fruit yield compared to the control. Depending on the applications, the fruit essential oil content varied between 1.94%-2.69% and the essential oil yield varied between 1.42-3.18 L/da. While the highest essential oil yields were obtained from 100 ppm GA3 and 50 ppm NAA applications, 1 mM MJ applications caused a significant decrease in essential oil yield compared to the control.

African eggplants are highly valued constituents of the Nigerian food. However, their nutritional potentials have not been fully tapped due to inadequate information on their nutritional and anti-nutritional qualities. This present study investigated the proximate, minerals, anti-nutrient contents as well as the estimation of mineral ratios and Mineral Safety Index of four selected edible solanum species namely, Solanum anguivi, S. gilo, S. menalogena and S. aethiopicum. The proximate contents (%) ranged from 4.19-5.46 (moisture content), 1.71-2.49 (crude fat), 4.57-5.45 (crude ash), 3.76-4.93 (crude protein), 5.20-6.30 (crude fiber) and 77.14-78.58 (carbohydrate). The solanum species were good sources of energy with total metabolizable energy of 1.458MJ-1.484MJ. The four solanum species contained high K, Ca, Mg, low Fe, Mn, Zn and Cu, while amount of Cd, Ni and Pb were very low. The mineral ratios of K/Na, Ca/Mg, Ca/K, Zn/Cu and [K/(Ca+Mg)] were below the minimum good ratios levels of 1.0, 4.17, 4.0, 8.0 and 2.2 respectively which are good for man. The anti-nutrient contents revealed low phytate, oxalate and cyanide levels. The calculated Phytate/Zn, Phytate/Ca and Oxalate/Ca were lower than the threshold levels and would support absorption and bioavailability of Zn and Ca in the samples while that of Phytate/Fe was above the critical value and this indicates unavailability of iron in these eggplant fruits. The mineral differences observed showed that S. menalogena and S. aethiopicum had greater minerals while the Mineral Safety Index results revealed that the body could not be overloaded with any of the minerals investigated. The eggplants are rich in fiber, ash, carbohydrate and minerals with moderate protein. The low level of the anti-nutrient is good and poses no deleterious effect when consumed. The eggplants have nutritional health benefits; hence, their consumption should be encouraged to address food insecurity in Nigeria

In this study, the effects of hazelnut husk (HH), peat (P) and growing medium consisting hazelnut husk + peat (HH:P) mixture on the growth of lettuce and some nutrient contents were investigated. In the experiment, vermicompost (VC) was added to 3 different media at a rate of 0-10-20-30-40-50% by volume. The research was carried out according to the randomized plot design with 3 replications. According to the research results, the fresh and dry weight of the lettuce plant, the number of leaves and the length of the leaves showed significant increases with vermicompost added to the media compared to the control, and it was determined that 40% vermicompost application to hazelnut husk and hazelnut husk+peat mixture was effective. It was determined that the root fresh and dry weight of the plant increased regularly with vermicompost applications and when the root development was evaluated in general, 50% vermicompost application on hazelnut husk+peat mixture and hazelnut husk were effective. Similarly, vermicompost added to the media regularly increased the total N, P, K, Mn and Zn contents of the lettuce plant. Considering the effect of the medias, the macro element contents of the plant were found to be higher in hazelnut husk and hazelnut husk+peat medium, Mn content in peat and Zn content in the mixture. When the effects on the growth parameters and leaf nutrient contents of the lettuce plant were evaluated, it was concluded that the addition of 40-50% vermicompost to hazelnut husk and hazelnut husk+peat media could be used as a seedling growing medium.

Yavuz Topcu
In recent years, climate change and Covid-19 pandemic have dramatically caused some attitude variation on consumers’ food consumption preferences. By measuring the impacts on their behaviors of these changes, using as a policy tool is of a great importance. This research was conducted to analyze the total effect of sensory quality and mediating effect with natural risk factor on veal consumption hedonism of consumers in Erzurum province under climate change and Covid-19 epidemic. The main data of the study was consisted of primary data obtained from 385 household in 2021. The data were used in basic effect model to measure the sensory quality effect on consumption hedonism, and then in mediating effect model to determine indirect effects of risk factor playing linking role. The results of the study indicated that sensory quality being of high total effect on consumers’ veal consumption hedonism in basic effect model explained 64% of total variance. On the other hand, it was determined that sensory quality’s direct effect on consumption hedonism in mediating effect model with risk factor was lower, but the risk factor’s indirect effect was meaningful, and had a higher explanation rate than that in basic effect model. In order to be able to increase consumption hedonism, human diets should include consumption based on alternative meat and protein sources of vegetable origin instead of veal consumption. Hygiene decisions minimizing Covid-19 infection risk, moreover, at production and marketing stages of alternative meats should be taken and implemented.
